This adventure, Five Deadly Shadows, is from Dungeon #195. A 4e adventure which I converted to 5e. I used this to show the players two things – the larger spiritual battle happening between Amaterasu and Tsuki-Yomi vs the oni god Fumeiyoshi. As well as the cultural difference between East and West in particular for a Japanese-analogue culture.
Apart from emphasising these powers through the adventure and making it explicit that the Five Deadly Shadows worshiped Fumeiyoshi I played the adventure as written.

Vanishing Strike. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) piercing damage, or 14 (3d6 + 4) if Kenzo has advantage against the target, and Kenzo becomes invisible until the start of his next turn.
Swift Rebuke (1/Day). When an enemy adjacent to Kenzo hits or misses him he may use his reaction to use vanishing strike against the triggering enemy and has advantage against it for that attack.
